If your company network is having problems and you need to troubleshoot it, you also need to know some basic information about the computers on the network. Internet Protocol is the underlying ...

The bits in the mask identify both hosts and subnets. The more hosts, the fewer subnets; the more subnets, the fewer hosts can be individually addressed. These bits become a tradeoff based on the ...

To connect some copiers or multi-function printers to a router, you may need to know the subnet mask value for the network. A subnet mask defines the value range of IP addresses used in a workgroup.

The last editionof this column discussed subnet masks and the nature of IP addressing. In this and the following column, we will begin discussing what subnetting means and how to do it. First, though, ...

The mask Class A subnet masks must start with 255.0.0.0 at a minimum, because the whole first octet of an IP address (the IP address describes the specific location on the network) is used to define ...

We have a pretty simple network at the moment that is going to get a lot more complex soon, so I'm trying to take it little steps at a time. All sites are connected via an AT&T MPLS, with one public ...

I set up a l2tp over ipsec vpn for a mac os x client. I can connect fine and I get an address, but the subnet mask is wrong (and corresponds to the class..). If I manually set the IP address and ...

The following summarizes how networks, subnetworks and hosts are identified in the TCP/IP protocol. An IP address is first divided between networks and hosts. The host bits are further divided between ...

For one to be able to create multiple logical networks within a Class A, B, or C network, one needs to know the principle of subnet. Without using subnets, one could only use a single network no ...
